# AWS Tools for PowerShell: logs leak IAM users' console passwords to local users

AWS Tools for PowerShell before 5.0.306 writes sensitive arguments into command output and log files. A local user on the same machine can recover an IAM user's cleartext AWS Management Console password.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed module version with `Get-Module -ListAvailable AWSPowerShell.NetCore` or `Get-Module -ListAvailable AWS.Tools.Common` and compare against `5.0.306`.
- Review PowerShell transcript and log files on shared machines for console passwords passed to cmdlets.

## Fix

- Upgrade AWS Tools for PowerShell to `5.0.306` or later.
- Patch any forked or derivative code that copies the affected logging behaviour.
- Until upgraded, avoid `-WhatIf` and `-Confirm` with cmdlets that take sensitive arguments.

### CVE-2026-107783 - Insertion of sensitive information into log file in AWS Tools for PowerShell

Bulletin ID: 2026-132-AWS Scope: AWS Content Type: Important (requires attention) Publication Date: 10/09/2026 08:30 AM PDT

Description:

AWS Tools for PowerShell V5 lets developers and administrators manage their AWS services from the PowerShell scripting environment. We identified CVE-2026-107783, where insertion of sensitive information into log file in AWS Tools for PowerShell before 5.0.306 might allow local users to recover an IAM user's cleartext AWS Management Console password from command output and log artifacts.

Impacted versions: <= v5.0.305

Resolution:

This issue has been addressed in 5.0.306 version. We recommend upgrading to the latest version and ensuring any forked or derivative code is patched to incorporate the new fixes.

Workarounds:

Avoid using -WhatIf / -Confirm with cmdlets that contain sensitive information in its arguments when using AWS Tools for PowerShell in versions <= 5.0.305.
